THREE-DIMENSIONAL GRAPHIC MACHINING DEVICE AND THREE-DIMENSIONAL GRAPHIC MACHINING METHOD

摘要

PROBLEM TO BE SOLVED: To easily create a curved surface because a curved surface that is finally acquired from an assembly drawing is predicted by creating an assembly drawing from graphic information of an assembly drawing that consists of one ore plural polyhedrons and creating a curved surface that is defined based on each vertex of the assembly drawing. SOLUTION: A graphic assembling means 1 creates an assembly drawing from graphic information that is inputted to an inputting means 100. A shape holding point setting means 2 sets a shape holding point based on shape holding point setting information that is inputted to the means 100. A detailed graphic creating means 6 consists of an adjacent graphic extracting part 3 which extracts an adjacent graphic, an additional graphic creating part 4 which creates an additional graphic and a detailed graphic creating part 5 which creates a detailed graphic and creates a detailed graphic based on the assembly drawing. A curved surface creating part 7 creates a curved surface that is defined based on each vertex coordinate of the created detailed graphic and the set shape holding point. A graphic correcting means 8 corrects an assembly drawing based on graphic correction that is inputted to the means 100.
